Taxa

a group/rank of organisms (species, family, class)

taxonomy

branch of science concerned with classification

phylogeny

study of evolutionary development and diversification of a species/organism

Mitosis

type of cell division; results in 2 daughter cells identical to parents

meiosis

results in 2 daughter cells; each with 1/2 the chromosomes of parent cell

haploid

having a single set of unpaired chromosomes

diploid

containing 2 sets of chromosomes, one from each parent

Binomial nomenclature

(genus species) ex. H. Sapiens

homology

similarity due to common ancestor (descent)

analogy

similarity due to common environment

monophyletic group

an ancestor and all its descendants

paraphyletic

missing a descendent

polyphyletic

with an organism that doesn't belong

endosymbiosis

one cells swallows a prokaryote but end up living together instead of being digested

protist

term used out of convenience, not a taxonomic group; eukaryotes that arent plants, fungi, not animals

slime molds

most closely related to amoebas; phagocytosis; cytoplasmic streaming; form large aggregates; reproduce via fruiting bodies and spores; come together and form a slug

rhizaria

typically long, thin pseudopod compared to ameobas

foraminiferans

marine; pseudopods stick out and capture prey and locomotion; secrete CaCO2 test-formed major limestone deposits in ocean

radiolarians

thin, stiff pseudopods stick out of test (assist in floating and increases surface area); marine zooplankton; heterotrophs, but may form symbiotic relationship with phototrophic microbial eukaryotes (algae)

metamonads

unicellular; flagellated; symbionts (mutualistic and parasitic); no mitochondria; anaerobic; known to have been lost (evolutionary reversal); excavate

euglenids

flagellated and flexible; excavate

glaucophytes

contain small amount of peptidoglycan on inside and outside of chloroplast membrane, same as cyanobacteria

Red Algae

multicellular; marine (most are tropical); photoautotrophs; some secrete CaCO3

Green Algae

photoautotophs; diverse morphology; unicellular; marine; temporal; multicellular filaments/sheets

Ciliates

chromalveolates; possess cilia for locomotion and feeding; unicellular; aquaticl feeding: oral groove, gullet; defense: trichocysts; H20 balance: contractile vacuole

acomplexians

chromalveolates; obligate animal parasites; unicellular; complex life cycles involging multiple hosts; cause of taxoplasmosis

acomplexian

cause of malaria (#1 infectious disease; affects red blood cells; transmitted by mosquitoes)

dinoflagellates

some cause "red tide"--release neurotoxins; vertebrates most affected due to bioaccumulation

diatoms

a very important part of the phytoplankton; unicellular; photoautotroph; widely used in paleolimnology; cell walls of SiO2

diatoms

toothpaste; metal polishes; pool filters

paleolimnology

study of reconstructing past environments

oomycetes

water molds and downy mildews; once considered fungi, but contain cellulose
